discovered certain new and useful Improvements in Sewing-Machine Guiding Attachments, of which the following is a specification, reference being had therein to the ac-1 companying drawings.

rlhis invention has for its object to p rovide an improved arrangement of sewing machine attachments, for use in corset work, and by means of which certain work hereto fore requiring three operations. may now be performed at a single operation. 'ln the manufacture of corsets the shaped sections of fabric, which are to constitute the body portion of the corset, have heretofore been first stitched together by seams running lengthwise of the corsets. A' transverse reinforcing waist band has then been stitched to the inside of the corset at a second operation, and the len thwise seam has been covered on the insi e of the corset, at a third operation, by a covering strip having inturned edges overlying and enclosing a reinforcing strip. ln accordance with the present invention, and by the use of a novel arrangement of sewing machine attachniente, this work, heretofore requiring the three operations above referred to, maynow.

be edected at a single operation, as will hereinafter more fully appear.

lnl the accompanying drawings Fig. l is a partial front side view, of a three-needle inger sewing machine equip ed with attachments in accondance with t e present invention. Fig. l is an enlarged detail view of sonie of the parts shown in Fig. l. Fig. 2 is a partial rear side view of the machine shown in Fig. l. Fig. 3 is a front end view of the same, with the parts beneath the work plate omitted. Fig. t is a partial plan view of the work-plate, with the attachments thereon. Fig. 5 is a detail section on line 5--5, Fig. t. Fig. 6 is an enlarged detail broken out section on line 6-*6, Fig. 3. Figs. 7 and 8 illustrate right and left lap-seam guides. Fig. 7m is a detail view showing the lap seam guide and the spring catch for removably attaching the same to its supporting bar. Figs. 9 and l0 are enlarged and somewhat diagrammatic views illustra' tive of the work performed by the use of the invention. l

Referring to the drawings, ll2 denotes a part of the work-plate ofthe sewing niachine, and l denotes a portion of the overhanging arm thereof. 'lfhis machine' coniprises a vertically reciprocating needle bar it carrying three needles 15, and a presserbar 16, to which is' attached a presser foot f7, properly constructed to (so-operate with the three needles referred to. "ll-wo of the needles are abreast of each other and the third needle is behind and in a line midway between the two needles in front, as will be understood from Figs. l and 3 and the positions of the searns indicated in Figs. 9 and l0. l'llhis arrangement of the needles adords more room for the arrangement of the coniplementary loop-taking devices arranged beneath the work-plate. ln the present instance the lifting arm i8, which is arranged for cooperation with the usual presser-foot lifter i9, instead of being attached directly to the presser bar, is carried by a sleeve le encirclin the said presser bar anc.- having a limite movement independentl of said bar. "Flic arm f8 is prov1ded wit a rearward extension arranged to be engaged by an inwardly extending lug 2ll at the forward end of the usual lifting lever 2l pivot-y ally mounted on the arm 13, and which lever 2l is, in the present instance, intended to be connected with a knee-operated lever, so that the presser-bar may be lifted by the attendant, when desired, without the use of hands. 'lihe extension 20 is provided with 'a pin22 connected by a coil spring 23 with a screw or pin 2t attached to the head or depending portion 13 of the arm ld.

Mounted on a slide 25, ntted to the workplate l2 of the machine, is a double folder and guide 26, adapted to turn in, upwardly, the opposite edges of a strip of fabric 27, the said folder and guide 26 being provided with a guiding slot- 28 abovethe strip slot 26%9 the slot 28 being of a suitable length to receive a reinforcing fabric strip 29 of a proper width to ht between the in-turned lll@ i' of the cutis lraider 2e. The a provided at its under. side with side lugs screw 36, to the depen 31 aifordi apassa way 31", between the body of sai plate ancglethe work-plate of the machine, for the two .combined strips ]ust referred to.

.. v (lo-operating with thefolder and guides\ just described is a lap-seam guide 32 pre the way when not in use, as denoted by v15 erably removably attached to the lower end of a vertically movable bar 33 adapted to.

slide `u and down -in afsleeve 34 carried by a b ock 35 pivotally attached, as by a ing portion or head 13a of the arm 13. The lap-seam guide 32 is arranged rearwardly of the folder and carried by a socketed shank 32n v guide 26, and preferably over the rear part of the guide .315A The lap-seam guide 32 is rovided with a' spring catch 32b by which said shank may be removably attached to a pin 33 on thebar 33. The lap-seam uide may have the. guiding ooves therein arranged to form either a right.l o r left guide, as shown in Figs. 7 and 8.

Attached to the top of said bar 33 is a. small plate 37 which extends laterally above a p1n`38 vcarried by a lever 39 pivoted at 'its rear end, at 40, to vthe head 13 and connected, between its ends, by a pin 41 and collar 42, toa rod 43 attached' at its -upper end to a lug 44 carried by the sleeve 18 encircling the presser bar 16. -Encircling the vrod 43, between the collar 42 and the lug 44, is a spacing sleeve 45, and a `coil spring 46 is interposed between the said collar 42 and a collar or head 45, at the lower end ofthe rod'43.

' The 4plate 37- is provided with a small lu 37a connected by `a..jcoil spring 47 to alu 48 attached to the sleeve 34,y so that t'he gar 33, and the lap-seam guide carried by the` said bar, will be held yieldingly downward by the slid spring 47. vBy virtue, however, of the lever- 39, connected as just described, through the lug 44, rod 43, collar 42 and pin 41, with the sleeve 18a enfact that there is normall circling the presser bar, and which lever V39 is also connectedi with; the indirectly knee-operated lifting lever 21, said bar 33, and the lap-seam guide carried thereby, may be lifted slightly, when desired, without lifting the presser-foot; by reason of the a slight space between the up er end othe said sleeve 18, and the li in collar 16a attached to the presser bar, said space permitting a certain amount of lost motion between said sleeve and collar. When, in the full operation of the lifting 'lever 21, the lost motion referred to has been taken up, both the lpresser-bar'and the bar 33 carrying the lap-seam guide will be lifted together, as may beV necessary in removing or replacing the work. A

The pivoted lblock 35, with which the lap-seam guide is connected, as above described, is normally rigidly fixed to the machine head 13a by aset nut 49 on a threaded Stud 49", and when the said set nut is loosened the said block may be turned on its pivot, afforded by the screw 36, so as to swing the lap-,seam guide up out of dotted-lines in Fig. 1; and the said guide will be retained in its swung-up position by the spring 50 attached to the face plate 51, said spring 50 then bearing against the lower ilat end of said block. Attached to the head 13 is a small block 52 which carries a stop screw 53 arranged to engage the block 35, so that the lap-seam guide may be properly positioned when returned to place after having been swung up out of the way.

ln the operation of the invention the fabric stri s 27 and 29 pass through the double fol er and guide 26, emerging therefrom in the relations and form illustrated in Fig. 9,- and in this form move forward beneath the guide plate 3l to the needles. At the same timelthe corset bodyA sections a and b, to be joined, are guided to the needles in overlapped relation by the la -seam guide 32, the cut edge of the section having been previously folded under and pressed down, as shown at b', so as to leave no raw edges protruding. The three needles, the ositions of which are denoted by the dotte lines c in Fig. 9, form three rows of stitches in the work, thus making a neat seam which is reinforced on the inside of the corset. by the Acovering strip composed of the strips 27 .and 29, disposed as denoted in Fig. 9, andbetween which strips 27 and 29 bone pockets e, extending lengthwise of the corset, are located.

The reinforcing transverse waist band d, to be stitched into the corset, will be held by Lhe attendant above the covering strip, composed of the strips 27, and 29, and in which th bone pockets e are formed, and beneath the corset body section pieces a and b, and when, in the pro ress of the sewing, the reinforcing band arrives at the lap seam guide the latter will be lifted slightly, without disturbing the presser foot, by the attendant, by a slight operation of the lifting lever 21, connected with the lap-seam guide-carryin bar 33, by the parts above hereinbefore escribed, to let the thickened ortion of the work at the waist band pass eneath the said lap-seam guide. Fig. 10 illustrates the relations of the several fabric parts at the waistband.

incasso a left hand guide, as shown in Fig. 8, will be used.

llt will thus be understood that by means of the invention herein shown and described the joining of corset parts, heretofore requiring three operations, may be edected at a single operation; thereby permitting the work to be performed much more expeditiously and at much less expense than heretofore. v f Having thus described my invention l claim and desire to secure by Letters Patent:
